Old example for laravel leads to out of memory php fatal errors - because it doesn't limit the number of stored items and at the same time doesn't have ttl, so cache is remembered forever. More than that, thanks to use of array_merge that leads to x2 memory usage (actually x3 because of inner Cache::put realization). So if your cache will have so much data what it weights about 100mb, php will require 300mb of memory during execution of old push method
